The loss of the leaving group is an essential step in many organic reaction mechanisms, particularly in nucleophilic substitution (SN1 and SN2) and elimination reactions (E1 and E2). A leaving group is an atom or group of atoms that detaches from the main molecule, taking with it a pair of electrons and thereby stabilizing the overall reaction.
A leaving group is an atom or a group that can detach from the parent molecule during a chemical reaction, leaving behind a reactive intermediate such as a carbocation or a negatively charged fragment.
The ability of a group to leave depends on its stability once it detaches; the more stable it is after departure, the better the leaving group it makes.
Alkyl Halides: Halides such as Cl, I and Br are common leaving groups due to their ability to stabilize the negative charge after they leave.
Water: In reactions where OH− is protonated to form H2O water becomes a good leaving group due to its stability in solution.

Overall Proton transfer is a fundamental process in chemistry where a hydrogen ion (proton, H+) is transferred from one molecule (the donor) to another (the acceptor).
Proton transfer can refer to either Protonation or Deprotonation.
Protonation adds a proton while deprotonation removes a proton.
